Title: Automatic document carrying device
IPC: B65H3/56
Filed: 1992-03-25
Abstract: PURPOSE:To eliminate malfunction such as overlap-feeding or non-feeding, by performing stable document-carrying with plural documents separated one by one. CONSTITUTION:A separation roller 6 and document stoppers 7 are supported with brackets 8 and 17 independent respectively. The diameter of the document stoppers 7 for a roller body is made smaller than that of the separation roller 6, and these document stoppers 7 are arranged in positions, slightly slipped to the center shaft of the separation roller 6, on both the sides of the separation roller 6, making documents abut the document stoppers 7 earlier. Recessed parts or holes 22 are formed under the document stoppers 7, making the document pass through the holes 22 or the recessed parts.

Title: Non-contact ignition system for magnet generator type internal combustion engine
Inventor: TSURUTA NOBUYUKI
IPC: F02P1/08
Filed: 1981-05-04
Abstract: PURPOSE:To suddenly delay an ignition timing at a high revolution speed by providing  a supplementary capacitor which bypasses an ignition signal of a signal convesion circuit, a revolution detective circuit and an amplifier circuit for an ignition system of a  magnet generator type to actuate a transistor in association with increase in revolution speed. CONSTITUTION:When a revolution speed is increased, an ignition signal bypasses a supplementary capacitor 15, which provides gradual ignition delay characteristics.  When a positive power is generated at a main capacitor charging coil 1, a supplementary capacitor 16 is charged with a certain voltage to get a polarity shown by the drawing. When a negative power is generated at the coil 1, a transistor 18 is conducted so  that a supplementary capacitor 17 is charged with electric load accumulated in the  supplementary capacitor 16 to get a polarity shown by the drawing and a voltage proportional to the revolution speed appears at the terminal of the capacitor 17. In a  low-revolution range, a transistor 19 is off and when the revolution reaches a high  speed range, an electric charge sufficient for turning the transistor 19 on is accumulated in the supplementary capacitor 17. Accordingly, the capacitor 17 is turned on and  the ignition signal is bypassed, so that an ignition timing is rapidly delayed. When the  revolution speed is increased up to the maximum, the rapid ignition delay ends.

Title: Thermal information recording medium and information recording method
Inventor: KITAJIMA TSUNEKICHI
IPC: B42D15/10
Filed: 1991-03-30
Abstract: PURPOSE:To make it difficult to identify a recording information from a recorded mark to prevent iniquities, such as interpolation, forgery, and modification, by a method wherein a dummy pattern is formed on a protective layer simultaneously with the recording of information in a pattern form on a thermal recording layer through the protective layer by a contact-type thermal printing means, such as a thermal head. CONSTITUTION:On a substrate 2, a thermal recording layer 3, a hiding layer 4 transmitting an infrared light for making said thermal recording layer 3 invisible, and a protective layer 5 having a melting point lower than a color- forming temp. of the thermal recording layer 3 are successively laminated. Therefore, a part of the protective layer 5 can be melted at a temp. lower than a color-forming temp. of the thermal recording layer 3 simultaneously with the recording of a normal information pattern 7-A by a thermal printing means, whereby a dummy pattern 7-B can be recorded without coloring the thermal recording layer 3. In this manner, the patterns 7-A and 7-B which are the same apparently are recorded in a line on the protective layer. The patterns are hardly discriminated apparently.

Title: Power source circuit
Inventor: YUDA TOKUJI
IPC: H02P29/00
Filed: 1985-03-30
Abstract: PURPOSE:To readily perform means for holding the short-circuiting state of a special load by forcibly discharging a charge stored in the second or following load in the state that a voltage is applied to the first load at a certain delay time when a power source is OFF. CONSTITUTION:After the power source voltage of a microcomputer load 2 rises when a power source is turned ON, the power source voltage of a motor load 1 rises. When the power source is interrupted, an IC17 erases a signal 102 at a certain delay time constant. Thus, a transistor Q3 is turned OFF to stop the operation of the load 2, and a signal 104 is generated from an IC13. Transistors Q2, Q1 are conducted by the signal 104, a dropper Q4 is turned OFF, and the charge stored in a capacitor C2 is discharged forcibly momentarily through a resistor R1, a diode D1 and the transistor Q1. At this time, a microcomputer power source, an initial signal 103 and the signal 104 are erased.

While a curve drawn from a point 53W54 is a part of a circle in larger radius than that of a circle 46 with a point 44 as its center. There are given a straight line drawn from the point 52W 53 and circular arcs in a small radius drawn from a point 14 to the point 51 and from the point 54W15. Accordingly, a delivery side chamber is never communicated to an operating chamber in a suction stroke, thus high efficiency of a compressor can be always maintained.

Title: Trigger switch
Inventor: FUJIMOTO KOJI
IPC: H01H21/00
Filed: 1989-03-20
Abstract: PURPOSE:To lengthen life and improve stability of operation by rotating a switching knob to move a movable armature while performing positioning and providing an on-off switch on a motor or on a circuit of power supply. CONSTITUTION:When a power supply switch 5 turns ON in the state of an A position, where one side movable armature 4a is positioned between fixed armatures 1a and 2b while the other side movable armature 4b is positioned between fixed armatures 1b and 2a, a motor M rotates in the prescribed direction. Next, when a switching knob 3 rotates in the right direction by 45 deg. to move to the N position, the one side movable armature 4a comes in contact only with the fixed armature 1a while the other side movable armature 4b comes in contact only with the fixed armature 1b. Consequently, even when the switch 5 turns ON, power supply is not performed to the motor M. When the knob 3 further rotates by 45 deg. to move to the position B, the one side movable armature 4a is positioned between the fixed armatures 1a and 2a while the other side movable armature 4b is positioned between the fixed armatures 1b and 2b. Thereby, when the switch 5 turns ON, polarity of the motor changes to perform reverse rotation.

IPC: H01J23/02
Filed: 1985-04-03
Abstract: PURPOSE:To eliminate any obstacle exerted on cooling air so as to improve the cooling efficiency of a magnetron by reducing the diameters of multiple permanent magnets which are piled up on the cooling air supply side of a vertical-blow magnetron, which is cooled by supplying cooling air flow in parallel to the tube axis. CONSTITUTION:A working cavity 13 is formed of a cathode 10 and an anode made of a cylinder 12 provided with vanes 11 which are arranged radially. A magnetic circuit is formed of permanent magnets 20, 30, magnetic poles 14, 15 and yokes 22, 23. A vertical-blow magnetron is formed of the above-said components with cooling air supplied from below in parallel to the tube axis by a blower 25. In this configuration, the lower permanent magnet 30 formed of multiple elements piled up vertically is made in the same diameter as the outer diameter of the anode cylinder 12 and is disposed so that its easily magnetized axis becomes parallel to the tube axis. Thus the permanent magnet 30 does not make an obstacle exerted on the cooling air flow which can therefore blow the cooling fins 24 effectively, resulting in improved cooling efficiency.
